Where I live all municipal workers, Police, Fire, garbage collectors; elevator installers, plumbers, welders, every blue collar profession you can name earn more money and have better benefits than the chemists. Around here chemists work via an agency to shield the company from employer laws, and pay $15 to $20 an hour no benefits, no career development, no raises, eventually you are fired with 1 phone call and no recourse and in some cases unemployment compensation (some companies declare you 1099 even though it is nearly always against the tax code).
And I know it might seem that way, but what you say is unlikely in many cases.
The median sanitation worker salary is from $9.50-$12.25 an hour. Yes, there are people that have been there a long time and get a lot more; but it is also hard work and LONG hours.
Police officer salary varies widely, but there are MANY places where they are only getting ~$20K a year. Seriously. And it is STRESSFUL and dangerous.
Firefighters do make good money. But they have a very dangerous and risky job. But in reality, 71% of the US firefighters are voluntary. Getting the paid firefighter gig is EXTREMELY competitive, in many places it is more competitive then getting into the most ivy league school you can imagine.
Welders, yes, if they are good, make damn good money. I have previously posted here to other people not sure about chemistry and just want to make good money. But, you have to be a good welder to make good money, and it is not as easy it it seems (I weld, trust me). Otherwise, just your average basic welder also gets $15-$20 an hour.
Real plumbers make good money; but there are very few real plumbers out there. Most that work in the plumbing field are just "technicians" and average from $9-$12.
I know it seems like they get more, and I am sure there are quite a few of those professions were people make more. But the hard truth of the matter is, they do not. If you are getting $20 an hour with a bachelors degree you are making 40+K a year. That is FAR higher then "blue collar" jobs. But the truth is, if you only have a BSc degree in Chemistry, you are only looking at specialized "blue collar" jobs that pay a little more then other people; unless you are lucky, or at a company with room for advancement.
You can keep saying all these false claims, but I am actually looking up these statistics from US labor sites; not just my feeling on what they make, or what I know one guy makes.
If you have a $40K a year job, you are making more money a year then 45% of the population makes with a dual income household!
I am sorry you feel entitled to be making more because you have a degree; but you are not.
